if you could explain exactly what you need i may be able to help more. are you asking about spacing or fit? might just need help decoding 670-1.
EDIT: for the Class A pants I suggest you go get proper fitting uniforms as soon as you can, the have them hemmed as soon as you can. Ensure they are the same fabric make up as your Class A jacket or others will be able to tell. There is also a wonderful little pocket sized cheat book on how to properly put together your uniform including a small ruler. Below you will see the majority of the guidelines. I suggest you also look in AR 670-1 to become familiar with how to properly use a regulation.
